Description

The machine includes a housing 1 with a mechanism 2 installed therein to create fluid pulsations. The mechanism 2 for creating fluid pulsations can be of any known type. The drawing shows, for example, a piston. The sections of the sieve compartment are installed with a transverse slope towards the outer wall of the housing and jigging sieves 3 are firmly fixed along the perimeter. In the outer wall of the sieve compartment, windows 4 are closed against each sieve in the interval between the lower edge of the scraper and the lower edge of the sieve; sealed rubber seals and screw clamps of any known construction. A scraper conveyor belt 6 is placed above the sieves at some distance from them. Holes 7 are arranged in the lower part of the sieve compartment for release of the understeer concentrate.

Works jigging maschina as follows.

The material loaded into the machine, in the process of transporting it with the scraper conveyor 6 over the jigging screens 3, is subjected to a long stroke jigging, after which it dehydrates on the inclined chute and is unloaded. Mineral grains (nuggets), larger than the diameter of the holes in the sieves, saturate the natural bed that fills the space between the scrapers and the sieves. Grain useful fossil size less diameter

holes in the slats are passed into the undersize concentrate, continuously released during operation of the machine through the opening 7. To periodically discharge the above-sieve concentrate (nuggets), the water level in the machine is lowered, the gates 5 are opened and through the windows 4 the concentrate is discharged, using a scraping device to remove part of it, which is not unloaded by gravity. The frequency of filming of the oversize concentrate from separate sections of sieves to be different depending on the content of large grains (nuggets) of minerals in the sand: for example, on gold, the subsequent sections can be removed much less frequently than the first material.

Subject invention

A jigging machine, comprising a housing with mechanisms installed therein for creating fluid pulsations and slashes, above which a scraper-conveyor belt is placed, characterized in that

reducing the laboriousness of removing the oversize concentrate and preventing coarse material from entering into the undersize space of the sieve are rigidly installed and arranged with a transverse slope to the outer wall of the housing, which, in the interval between the lower edge of the scraper and the lower edge of the sieve, has openings for unloading of the above-mentioned concentrate equipped with gates.
